The Dark Saber is the weapon of choice by the Evil Undead Knights. Thought to have originated when one of these knights stole the sword of a low level hero. The sword was corrupted by the evil within the knight, and thus forged a new weapon, the Dark Saber.

Alternatively, the Dark Saber is a weapon from a TV show that no longer exists, thus increasing its rarity. This show was from famous god Leorge Gucas, but was destroyed by Dalt Wisney.
